Application filed October 14, 1912. Serial No. 725,720.

To all 2071 (m2. it may concern.

Be it known that we, ami-1n H; Snrrn, of Niles, and CHARLES .l'.\Vnunrr, of \Varrcn. both in the county of Trumbull and State of Ohio,have invented certain new and useful Improvements in Delivery Mechanism;and we do hereby declare the follow .ing to be a fall,v clear, and exactdescription of the invent-ion, such as will enable l-hers skilled in theart to which it appertains to .makcand use the same.

The primary object of this invention is to provide improved deliverymechanism for printing and like'presscs, by which stock may betransferred from thcqiress to a receiver or jogger-board at a slowerspeed than thatat which it is discharged by the press, and.thus lessenthe chances of injury to the stock which is liable to occur when thespeed of travel to the deliverer is as fast as the face-speed of theimpression-cylinder.

, A further object to enable thereceiver,

or jogger-board, to be readily adjusted and heldin dilfcrent positionsrelative to the delivery mechanism while the latter is in operation. 4

In the accompanying drawings, Figure l I Fig. 2 is a planview with partsomitted. Fig. 3 is a section through a gripper mechanism. Fig. 41. is adetail. Figl 5 is a fragmentary rear view. Fig. 6 shows a modification.

Referring to the drawings, 1 designates a printing press frame; 2 theimpression cylinder, a part only of which is shown; 3 a

shaft-mounted in frame 1; and 4 a gear wheel on said shaft which-ispreferably in meslrwith and driven by the impression cylinder gear. onshaft 3 are two sprocket wheels 5 which are of less diameter than gea r4 and the corresponding. gear of theim prcssion cylinder. 6,6 designatetwo spaced-apart sprocket chains which engage with wheels 5 and alsomwith two smaller sprockctwheels'7, which latter are mounted. on a crossrod 8 supported by side rods 9 of an extension frame, these latter rodsbeing held by adjustable uprigl-lts 10. .These chains carry means fortransferring stock from the press, and such means xwhilc traveling withthe carrier chains: will. when ii'njuxtapositicm to the press-cylimlcr,travel at the face ,speed of such cylinder, but for the ma orportmnot;-.t,l c.t-ra vcl thcstock-engaging means will ing' the grippers.

. 3 move at a lesser speed than the face speed of the cylinder. Thespeed of travel of the carrier, however, remains constant. In thepresent lnstance we have shownv the stockengaging means in the formergrippers, in three separate sets, but the number maybe varied, as may,also the distancebetween the various sets. We have found that advantmgeous resultsare obtained musing three sets of grippers so that eachsheet as it is being transferred to the receiver. or jogger-board, 11,will travel approximately one third slower than the face speed of thepress cylmder. The particular construction of the grippers may be widelyvaried. According .to the means shown,',eachset comprises a rock-shaftl2 carrylng grippers '13 which are normally held in'engagementwithcollars 14 on a rod 15 paralleling and in close relation to grippershaft 12. The latter and said rod travel on a different plane from thatof the carrier, that is, they are held outwardly away from the latter.The means shown for this purpose consists of frames 16 secured to thesprocket chains. The grippers are normally held inengage ment withcollars 14 by a spring 17 attached to and wound around the gripper shaftand fastened to framelG. At one end each gripper shaft 12 carries an arm18 hearing at its free end a frictional roll which upon engagement witheither of two cams, 19, 20, will effect the opening of the grippers.

The cam 19 is located. in close relation to the impression cylinder andis designed'to open the grippers atthe proper point to re ceive thestock from the impression cylinder. This cam is shown as mounted on anarm 21 loosely journaled on shaft 3 and to which arm an adjustingrod 22is connected, said rod being adjustably held to a noddle pin 23 by nutson opposite sides thereof which allow the rod to he adjustedv toposition the cam at the proper point-for operaterating cam, 20, isadjustably secured to an arm 24 fast on-cross rod 8, andthe function-ofthis cam is to cause the grippers of the delivery mechanism to releasethe stock at the desired point for discharging onto the 105 By adjustingthis cam, the 'Ul'llc .of opening. the grlppers may be i izer-board:

.In or er to obviate vibration which is liable to occur, especially inlarge presses between the gripper shafts'of the delivery mechanism andthe im ression 'eylinder, when 'the fOrmerare Ina ing the turn beheathsuch cylinder, we mount on shaft 3 a wheel 35 having in a segmentalcut-out a notched plate 36 engaged by two rollers carried a commonframe. 37 mounted on'each gripper shaft and its cooperating rod 15, thecenter of the rollers being the pitch line of sprocket wheels 5. Uponshaft 3 we also mount a sedisks 10 of the same diameter as theimpression cylinder or cylinder from which the sheets are'to be taken,so that while, the grippers of the deliverer are traveling at arelatively increased speed and moving around with these disks, the stockfrom the cylinder will the face speed of the impression cylinder 1 pileof sheets to be readily i pr fb eis the size of the press, so that whilethe sheets are traveling be supported by the latter. These guides may beofany desired formation. The grippers continue to .travel at'thefacespeed of the press-cylinder until they reach the point V, Fig. 1,when they travel in a horizontal plane at a greatly reduced.

speed, that is to say, at about two-thirds the face speed of thepress-cylinder.;.

The diameters of the respective parts may be widely varied, and likewisethe number of gripper sets and the distance between the difierent setsmay tered. According to the means shown the spacing of the gripper setsis approximately sheet being run through the from point V, Fig. 1, tothe dischar ing point, they stand practically end-to end although theyare separated a greater distance on the impression cylinder. As theseveral sets of grippers begin totravel at they are severally opened toreceive the sheet from the impression cylinder by the engagementof'their arms 18 with cam 19, and as the sheets reach the limit of theirhorizontal travel away" from the press they are released by theengagement of said arms with-cam 20, and being stripped by fingers 30,they'willfall on jogger-board 11. This jogger-board at its rearend, isprovidedtally which is designed to bev their travel.

turned. Arms 1 6 carried by this cross rod 43 are connected by links 17to castings 48 on the underside of the board, near the forwardend'thereof. Hence by manipulating handle 15 the jogger-board may behorizonadjusted, and it may be held at the desired point by a set screw50 projecting through'an arcual slot in a fixed plate 51.

In practice the operator first adjusts the jogger-board according to thesize of the sheet it is to receive and likewise adjusts the two cams 19and 20 to nsure the opening of the grippers at the necessary points inAs each set of grippers is brought into proper relation to ,the. presscylinderthe'sheet will be taken from the latter and held by the grippersagainstcollars 14- of the cooperating rods 15. Atthis 1 time, and alsoduring the time required for the withdrawal of the sheet from the presscylinder, the grippers of the deliverer will be traveling at the facespeed of the press cylinder, but coincident with which thegrippers'leave the guide-wheels 10, the sheets will travel at a reducedspeed.

When the gripper actuatingarm engages' cam 20 the sheetis releasedanddeposited on the receiving table.

It is manifest that the inv'ention'is :open to various modificationswithout departing from the essential idea of having the stockengagingrippers travel at a differential speed the point at where'hjthe stockmay be deposited at a speed lessthan the face speed of thepress-cylinder. While for all practical purposes the stock maybedischarged whilethe grippers are in motiombut at faless speed,

than the face speed of the press cylinder, yet if desired the grippersmaybe brought wholly to rest at the time of't-hedischarge withoutstopping the operation of the gripper-carrier. Thus, in' Fig. Gwe haveshown diagrammatically an arrangement of this character, wherein thelower, or outward flight of the delivery "chain 1s passed over an1dler-sproeket 55located at a point near the outer sprocket of thecarrier chains In passing over this idler sprocket 55 each set ofgrippers is brought to a standstill} during that period of timefrequiredfor th'ecarrier chains to move or cover the 'distancerepresented bytheiangle X. In this way each sheet is brdifght to a stop, or ceases totravel, although tli'e cjarrier continues to run at its, uniformspeeld',' there being no time that the carrier chains and sprockets donot revolve uniformly. Wehave shown the lower flight of the chain asbeing carried up" an incline in approaching sproeket'55, but this is'notHence it will be seen that accord-I ing to our to transfer the sheets ata slower s' eed than the face spec?i of the press cylin er, but it isalso possi e, without interrupting the uniform travehof the 'carrier,'tobring the a m5 invention 1t 15 notonly possible their travel while thegrippersto a complete stop at a portion of stock is being released. y an sprocket, an necessarily the position of the releasing cam, in runningsmall sheets they may be dropped at any place at 'wilL' 7-; In Fig. '6the height of the grippers relatively to the "diameter of the sprocketis somewhat exaggerated. idler sprocket should have a radius equal tothe height that the grippers are above-the pitch line of, the carrierchain, that is to say,

if the height of the grippers. is two inches above t'he 5pitch line ofthe chains when assing around the guiding disks/l0, the 1dlersprocketshould be four inches in diameter to enable the grippers and sheets tobe brought to astop through a portion of the travel around thesprocket.,.
